(Senior) Software Engineer (m/f/d) Network Security

Our mission is to lead the transformation to a company-wide platform approach by developing and maintaining shared infrastructure and services as strategic assets. We enable scalable, efficient product development and foster innovation across the organization, empowering teams to deliver value faster and more effectively. We provide the technical means to develop entirely new product classes.

Our team of highly motivated software engineers focused on cutting-edge, security-focused technologies and a DevSecOps platform that supports the entire lifecycle of our products. We deliver measurable business impact by enabling faster time-to-market, reducing development costs, and improving product quality through scalable and reusable services & components.

To enable the product teams, we're building an operating system based on NixOS that is image-based, immutable, and puts a heavy emphasis on security and reliability. We leverage modern security features like dm-verity, Post Quantum Cryptography (PQC), systemd sandboxing, Secure Boot, Measured Boot via TPM2. We consider all aspects of the operating system starting from booting to bootstrapping trust in dynamic environments to providing secure networking.

Our tech stack

• NixOS and thus Linux as the basis for our OS
• Rust for all components we develop
• Nix as our meta build system
• NixOS VM test framework as the basis for all our integration tests
• GitLab as the control plane for our development
